Table 10-5: Routing Parameters
Parameter Description
Routing Select 'Advanced' or 'Basic' routing.
Routing Mode Select one of the following Routing modes:
Route Use route mode if you want your device to function as a router between
two networks.
NAT Network Address Translation (NAT) translates IP addresses to a valid,
public address on the Internet. This adds security since internal LAN
addresses are not transmitted over the Internet. In addition, NAT allows
many addresses to exist behind a single valid address. Use the NAT
routing mode if your LAN consists of a single device, otherwise collisions
may occur if more than one device attempts to communicate using the
same port.
NAPT Network Address and Port Translation (NAPT) refers to network address
translation involving the mapping of port numbers, allowing multiple
machines to share a single IP address. Use NAPT if your LAN
encompasses multiple devices, a topology that necessitates port
translation in addition to address translation.
Device Metric The device metric is a value used by the device to determine whether one
route is superior to another, considering parameters such as bandwidth,
delay, and more.
Default Route Select this check box to define this device as a the default route.
Routing Information
Protocol (RIP)
Select this check box to enable the Routing Information Protocol (RIP).
RIP determines a route based on the smallest hop count between source
and destination. When RIP is enabled, select the following:
Listen to RIP messages Select 'None', 'RIPv1', 'RIPv2' or 'RIPv1/2'.
Send RIP messages Select 'None', 'RIPv1', 'RIPv2-broadcast' or 'RIPv2-multicast'.
Multicast IGMP Proxy Internal IGMP proxy enables the system to issue IGMP host
messages on behalf of hosts that the system discovered through standard
IGMP interfaces. IGMP proxy enables the routing of multicast packets
according to the IGMP requests of LAN devices asking to join multicast
groups. Select the 'Multicast IGMP Proxy Internal' check-box to enable this
feature.
Routing Table Allows you to add or modify routes when this device is active. Use the
'New Route' button to add a route or edit existing routes.
